For a richer flavor, use dark chocolate chips instead of semi-sweet. To prevent the bottom from over-browning, line the jelly roll pan with parchment paper. Store the bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. For a fun twist, add a layer of chopped nuts (such as peanuts or pecans) between the chocolate and frosting layers.

Oct 2, 2024I added a sprinkle of sea salt on top of the chocolate layer before it cooled, and it really enhanced the flavor. Highly recommend!
